Patent GB-896238-A (GB)
Title: An electro-hydraulically actuated electric multiple switching device
IPC: F15B21/08
Filed: 1959-12-22
Abstract: 896,238. Control of motors; controllers; fluid actuation of switches. LICENTIA PATENTVERWALTUNGS G.m.b.H. Dee. 22, 1959 [Dec. 29, 1958], No. 43533/59. Addition to 838,971. Classes 38 (3) and 38 (5). [Also in Group XXIX] A piston 3, for actuating an individual heavycurrent contact or group of contacts, forms part of a structural unit 1 mounted on a base-plate 27. Energization of electromagnet 11 causes armature 14 to press pin 57 and needle valve 50 downwardly, so closing passage 54 and opening passage 53 whereby oil passes through bore 46 to displace piston 6 towards the left against the pressure of spring 39. This opens inlet 42 so that oil passes from bore 7 through bore 59 and acts upon the piston 3 which executes the stroke for effecting a switching operation. An extension 25 of the unit 1 co-operates with a recess 26 in the base-plate, a locking claw 29 being provided. A number of units may be mounted on the same base-plate. Bore 30 in the base-plate acts as a supply passage for the oil for actuating the piston 3, whilst bore 31 is similarly associated with the piston 6. Bore 35 allows interconnection with other units. When the electromagnet is de-energized, spring 52 closes passage 53 and opens passage 54 so that the piston 6 is displaced towards the right under the action of spring 39. In this position, outlet 43 below the piston 3 is fully open and the piston drops. A ball-valve 55 prevents back-flow of oil into the supply-line 7.

Title: Process for the production of polycarboxylic acid salts
IPC: C08G2/00
Filed: 1965-10-14
Abstract: An alkali-metal salt of a polycarboxylic acid is obtained by forming a polyaldehyde by polymerizing an unsaturated aldehyde by a Redox polymerization process in which a silver salt constitutes the reducing agent of the Redox system and a peroxydisulphate constitutes the oxidizing agent of the Redox system, making alkaline the medium in which the polymerization has been carried out by adding alkali-metal ions thereto and thereafter oxidizing the polyaldehyde in situ in the polymerization medium which has thus been made alkaline using an oxidizing agent comprising cupric oxide or cupric hydroxide, whereby the desired alkali-metal salt of the polycarboxylic acid is produced.  The cupric oxide or hydroxide may be precipitated in situ in the polymerization medium.

Title: Improvements in or relating to matrix circuit arrangements
Inventor: BIRT DAVID ROBERT
IPC: H04N9/67
Filed: 1963-11-06
Abstract: 1,058,129. Colour television. MULLARD Ltd. Nov. 6, 1963, No. 43802/63. Heading H4F. [Also in Division G4] To obtain the G-Y colour-difference signal by combining the R-Y and B-Y colourdifference signals, a colour television matrix arrangement as shown in Fig. 4 is used wherein the signals - (R-Y), - (B-Y) and a D.C. bias are applied to terminals 1, 2 and 8 respectively and by selecting appropriate feedback resistors R 9  and R 10  the G-Y signal is obtained at the terminal 4 which is connected to a variable tap on anode resistor VR 8 , the R-Y and B-Y signals also being obtained at terminals 3 and 5 which are connected to variable taps on anode resistors VR 7  and VR 9 , respectively. Because the circuit is cathode-coupled it does not produce a coloured hum-bar and it has a good highfrequency response, and in addition the circuit is not very susceptible to variations in circuit components. By inclusion of a cross-talk resistor R 12  the cross-talk is reduced between terminals 3 and 5 from 5% to 1%. To substantially remove cross-talk, cancellation resistors R 13 , R 14  and R 15  are connected as shown in Fig. 5 and their values are selected to satisfy certain conditions (see Specification). Resistor R 14  may be connected to the zero potential terminal 7 instead of the anode supply terminal 6 and in this case one or more blocking capacitors are included in series with the cancellation resistors to prevent any direct current drain from terminal 6 to terminal 7. The Specification includes values of the circuit components shown in Figs. 4 and 5 and states that transistors may be used instead of thermionic valves.

Title: Pellets and their production
IPC: B01J2/22
Filed: 1972-09-26
Abstract: 1364150 Ore pellets; silicon carbide F O WIENERT 26 Sept 1972 44418/72 Heading C1A [Also in Divisions B5 and C5] Rounded pellets, especially of carbon-reducible iron ores or of carbon, are formed from a mixture of particles and an aqueous liquid by vibrating the mixture whilst rolling it into a dense uniform layer, dividing this mass into equal pellet-sized bodies, rounding the bodies into pellets and drying them. The amount of liquid present in the mixture should exceed that held by the densely packed particles, the amount of the excess depending upon the particulate material. The mixture may be fed to a conveyer 13, having side plates (not shown), whereon it is doctored by a roll 21, and compacted by a pair of rolls 27 carrying a vibrator 31. The compacted layer is sliced into strips by slitting knives 33, the strips being cut transversely into cubes by a flying cutter 35. The cubes fall on to a sloping oscillating table 39 where they are rounded. This table may additionally be vibrated and provided over its surface with rounded protuberances. Other tumbling means such as a rotary drum may replace the oscillating table. Drying may be effected by hot gas, or by coating the pellets with powder which may remain thereon to form a shell either of the same or a different composition. In an alternative arrangement (Fig. 2, not shown) the compacting vibrator is below the conveyer and the two cutters are replaced by an endless belt mechanism comprising hinged sections of width equal to that of the compacted layer and each comprising a grid which is brought down on to the compacted layer to penetrate it, assisted by a vibrator, the cut out pieces then being discharged on to the shaking table as before, a further vibrator being used to assist in dislodging them from the grid. After partial drying the pellets may be impregnated, or the coating thereon impregnated with binder in a liquid, e.g. water and then completely dried. Examples 1 to 5 describe in detail the use of the method for producing pellets of various iron ores, the green pellets being dried and hardened by hot oxidizing gases. A small quantity of bentonite may be added and the ore-bentonite powder may be used to coat the pellets during tumbling. Bituminous coal may be used with coarse titaniferous magnetite ore, the proportions being such that upon heating the pellets in a kiln most of the oxide is reduced to metallic iron and sufficient carbon is left to reduce and combine with the titanium when the pellets are subsequently smelted. The dried pellets were cooled in an inert atmosphere. Partially pre-reduced iron oxides may be used and blast furnace dust, other waste ferrous material, and coke breeze may be included (Examples 6-7). Iron-oxide with carbon pellets may have limestone particles added to improve desulphurization during smelting (Example 11). Other oxides may be pelletized by the method, Example 12 describing pellets formed from silica, coal, pitch and tar.

Inventor: WOODCOCK RICHARD FORREST
IPC: H01J29/89
Filed: 1965-10-21
Abstract: <PICT:1079969/C1/1> A cathode-ray tube faceplate, composed of a multiplicity of optical glass fibres hermetically sealed together in side-by-side relation, has a tapered, even, edge which is hermetically sealed to a corresponding tapered inner surface of an annular glass frame by means of which the faceplate may be sealed to the funnel portion of a cathode-ray tube envelope.  The optical fibres may comprise cores of optical flint glass, each with a cladding of crown or soda lime or potash soda lead glass, elongated fibres being stacked under pressure and fused together in vacuo to form a sealed bundle which is sliced to form faceplates, the edges of which are tapered by grinding.  The faceplate 21 is then assembled in the glass frame 15 of potash soda lead glass supported by a refractory block 24, a small space being left between faceplate 21 and block 24 to permit slight downward movement of the faceplate during sealing by fusion but preventing any tendency for the cores of the fibres to flow outwardly of their claddings. Alternatively, the opposite face of faceplate 21 may be supported by a refractory block, the frame being fitted thereover, Figs. 7 and 10 (not shown). Instead of fusing the frame directly to the fibre faceplate, a sealing of flux glass powder, e.g. Pyroceram cement, mixed with a binder may be applied to one or both of the mating surfaces.  Either or both of the light receiving and emitting surfaces of the faceplate may be curved, and the faceplate may be composed of tapered fibres, Fig. 9 (not shown), to provide magnification or demagnification of light images.
